Application filed February 18, 1913. Serial No; 749,208

To all whom it may concern j Be it known that We, PETER VVILDE and LOUIS WILDE, citizens of the United States, residing at Fort Laramie, in the county of Goshen and State of WVyoming, have invented certain new and useful Improvements in Cutter-Bars, of which the following is a specification.

This invention relates to improvementsin cutter bars, and more particularly to the mounting for the sickle. y j

The object in view is the elimination of friction by the employment of anti-friction means adapted to be effectively sustained in position during use and yet readily accessible and designed for easy access and replacement.

The invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter described and claimed.

In the accompanying drawing :Figure l is a plan view of a fragment of a sickle bar and connected parts embodying the features of the present invention. Figs. 2 and 3 are cross sectional views taken respectively on the planes indicated by lines 2-2 and 3 3 of Fig. 1. Fig. 4 is a detail, fragmentary section illustrating some of the parts seen in Fig. 2 on an enlarged scale. Fig. 5 is a similar view with respect to some of the parts seen in Fig. 3. Fig. 6 is an enlarged, detail, perspective view of one of the bearing sleeves detached.

Referring to the drawing by numerals, 1 indicates the shoe and 2 the cutter bar which latter is provided with the guard fingers 3 and guard plates or sickle holders 4. The guards 3 are of the ordinary construction except that each is detachably connected to the bar 2, as for instance by a screw 5 passed through the inner end portion of the respective finger and threaded into the bar. The sickle holders or plates 4L are also of ordinary construction except that they are also detachably connected, as for instance by screws 6, 6 passed through the respective plates and threaded into the bar 2.

Disposed to be guided between the holders 4L and the fingers 3 is the usual sickle comprised of the scythe bar 7 and the sickle blades or sections 8, the latter cooperating with the usual ledger plates 9 carried by the guard fingers 3. Each finger 3 is formed with a transverse notch for snugly accommodating the scythe bar 7, and beneath the notch the respective guard finger is formed with a recess shaped and adapted to accommodate a bearing roller 9, the recess extending longitudinally of the finger at one end of the roller and being supplied with a bearing sleeve 10 in which is journaled the outer end of a shaft 11 carrying the roller 9. At the opposite end of the recess, the bar 2 is recessed for accommodating a hearing sleeve 12, similar in construction and arrangement to the sleeve 10 and disposed for acconnnodating the other journal end of the shaft 11. Each sleeve 10, 12 is preferably externally rectangular and fits snugly in its respective receiving recess so as to be firmly held in place, and at the same time adapted for removal and replacement. It is to be particularly noted that as the shaft 11 has one of its terminals mounted in the bar; 2 and its other journal mounted in the respective guard finger, the detachment of the guard finger by the removal of the belt or screw 5 will enable withdrawal of the shaft 11 from the sleeve bearing 12, and after the detachment of the respective finger the shaft may be withdrawn from the sleeve 10, and the roller 9 thus readily removed and replaced.

Each plate or sickle holder :1 is disposed at a point intermediate adjacent guard fingers 3 and a vertically disposed shaft 13 is mounted or journalcd in each plate a, the upper end portion of the shaft engaging the respective plate and the shaft extending thence down- \vardly and finding a bearing in the bearing sleeve M which is similar in construction and arrangement to sleeve 10 but disposed vertically instead of horizontally and mounted in the bar 2. An anti-friction roller 15 is carried by and may be rotatably mounted upon each shaft 153 and is so disposed as to engage the rear edge of the sickle, the edge of the scythe. bar and of the several blade sections resting against the several rollers 15. It is to be noted that the parts of the several anti-friction elements 15 are rendered accessible by virtue of the employment of the (letachablc screws or bolts 6 which enable the ready removal of any one of the holders 4, and upon such removal the respective shaft 13 may be withdrawn and the correspoinling roller 15 reu'loved.

The operation of the structure is, of course, perfectly obvious, being similar to like structures, the stroke of the sickle being largely remlered frictionless by the anti-
